How the Eye Works?

1. The Cornea

The Cornea is a curved dome of strong, clear tissue on the surface of the eye, the cornea focuses light onto the retina.


2. The Epithelium

The epithelium provides a thin protective layer for the cornea and heals very quickly when disturbed.


3. The Iris

The Iris is the coloured part of your eye and is actually a muscle that controls the size of the pupil.


4. The Pupil

The Pupil is the black circular area in the middle of the eye. It controls the amount of light reaching the retina.


5. The Retina

The Retina is a membrane on the inner wall of your eye, similar to the film in a camera, the retina changes light into images that are transferred to the brain via the optic nerve.


6. The Sclera

The Sclera is the outer white coat of the eye, the sclera also provides protection.


7. The Lens

The natural lens behind the pupil changes shape to allow the eye to focus. As you age, your natural lens hardens resulting in presbyopia-the loss of reading vision.
